PROFIBUS DP communication

9.1.4.1 PROFIBUS DP configuring

The ASM 452 is integrated into the hardware configuration by means of a GSD file. The
ASM can then be configured using the HW Config of SIMATIC Manager or another
PROFIBUS DP tool.
A GSD file is provided for ASM 452 on the "MOBY software" CD.

9.1.4.2 Operating mode of the ASM 452

The approved operating modes of ASM 452 are described in the GSD file. It is set using the
hardware configuration tool (e.g. STEP 7 HW Config).

9.1.4.3 PROFIBUS DP diagnostics

The following table lists possible error indications with their meanings and provides
remedies.
